FUEL-HEATING DE YICE FOR INTERNAL-COMBUSTION ENGINES.

To all whbm it may concern:

Be it known that 1, CHARLES L. RODGERS, a citizen of the United States,residing at Newton, in the county of Harvey and State of Kansas, haveinvented certain new an useful Improvements in Fuel-Heating Devices forInternal-Combustion Engines; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to Which it appertains to make and, use thesame.

This invention relates to a fuel heating device fori internal combustionengines, by the use of which, kerosene and heavier hydrocarbon oils orliquids maybe used as a fuel for the same. vAs a feature of theinvention, the exh'aust from the explosive engine is utilized as a meansoil, and converting the same into a gas or vapor before it is introducedinto the firing cylinders.

Another object of the invention is to pro vide a device of thischaracter which may be readily "applied to or removed from explosiveengines of any construction or character, and one taken apart forcleaning or repairs.

An additional'object of the invention is to provide'an attachment forinternal combustion engiiies'which will act to thoroughly mix themixture in addition to thoroughly A further object ter by providing adevice which will be extremely simple, durable, and inexpensive inconstruction, and one which will be eflicient and .reliablein operation,and well adapted I features of construction and the and arrangement tothe'purpose'for which it is designed.

With these and numerousother obj ects in the-invention consists ofcertain novel combination of parts as will be hereinafterfully-described and claimed.

The accompanying drawings illustrate the view,

construction of the preferred, form of the in-. .ven'tion and the mannerin which the same is applied to an'internal combustion engine, andwherein: Y

Application filed October 2, 1916. Serial No. 123,386.

Fig. 3'is a vertical sectional view of the device detachedfrom theengine; and

a horizontal sectional view of the Fig. 1 is plane indicated by thedevice taken on the (1 .line H of Fig. 3.

Referring more particularly to the drawings 1n which like parts aredesignated by similar reference characters throughout the several views,the numeral 1 represents afitted and secured in any suitable manner theends of a plurality of tubes or pipes 3. As the tubes 3 extendlongitudinally through the casing 1 and are staggeredly arranged whenviewed from the side to provide an eflicient fuel mixing dev ce to bemore fully hereinafter. explained. Two of the opposite sides 1 of thecasing are provided with openings 5, the opening 5 in one ofthe sidesbeing'adapted to receive the short pipe section or nipple 6 leading fromthe carbureter of the internal combustion engine, while the opening 5 inthe other side ofthe casing is adapted to receive asimilar leading tothe intake manifold of said engine.

Arranged at cap members 8 10 and flanges 11, free edges abutting 1 asclearly shown by the drawings. The ends 10 of the cap members 8 and 9are provided with inlet and outlet openings12 and 13 respectively, theopening 12 being adapted to receive one end of the exhaust pipe 14leading from the engine, while the other opening 13 is adapted toreceive one end of an exhaust escape pipe 15. Extending longitudinallythrough the casing 1 and the cap members 8 and 9, are clamping bolts 16having nuts 17 on their threaded free ends, whereby said cap members areremovably held in their assembled positions, with respect to the casing.

, It is here to be noted that the cap members conform to the shape ofthe casing, -but if desired, they, together with the casing, may be madeof any suitable shape. The number and size of tubes and size of thecasing is to be determined by the type and size of engine in connectionwith which the device is to be 1 are provided with a plu-v rality ofapertures 2 in which are snugly.

the ends of the casing 1 are i and 9 composed of end plates the latterhaving their the ends of the casingv Mid ' 'It has been found that whena device constructed in the manner above described is used in connectionwith an internal combustion engine, the heat radiated from the tubes 3by the hot exhaust ases passing through the same will be su cient tocompletely vaporize the kerosene or other heavy hydrocarbon oils used asa fuel for the engine. As the fuel passes transversely through thecasing and around the tubes, which are, as previously explained,arranged staggeredly, it will be thoroughly mixed.

Another advantage of the invention resides in the fact that the devicemay be readily and easily taken apart for cleaning or repairing, andalso it may be readily and easily applied to or removed from an engineof almost any type.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and use of the invention will bereadily understood without a 'Inore extended explanation.

As numerous changes in form, proportion, and in the minor details ofconstruction, may be resorted to without departing from the spirit ofthis invention, I do not wish to A device of the class describedcomprising a hollow rectangular shaped casing havin a plurality ofapertures in the ends thereo and gaseous fuel inlet and outlet openingsin two of its opposite sides, a plurality of tubes extendinglongitudinally through said 7 casing and having their ends secured insaid apertures, rectangular shaped cap members composed of rectangularshaped end plates and inwardly extending lateral flanges, said endplates being provided with inlet and outlet exhaust openings, said capmembers being arranged at the ends of said casing with their flangesabutting the same, and clamping bolts extending longitudinally throughsaid casing and said cap members for removably maintaining the latter intheir assembled casing.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
